Invoking a web service: Object reference not set to an instance of an object

Summary

When
consuming a web service through SOAP
protocol, an XML
file which contains a structure with methods and parameters is always
required by the web service, this file is known as WSDL. When
the parameters or methods defined in the XML are named using reserved
characters for Bizagi (e.g. the dot “.”), the file mapping process will
return an error and the web service will not be reached.

Applies to

Symptoms

problems related to object references

Cause

It is possible that the WSDL uses
